On March 30, 2020, the partnership contributed our U.K. regulated distribution operation and Brazilian regulated gas transmission operation to BIPC. On March 31, 2020, the partnership completed a special distribution (the “special distribution”) whereby unitholders as of March 20, 2020 (the “Record Date”) received one class A exchangeable subordinate voting share (“BIPC exchangeable share”) for every nine units held. Immediately prior to the special distribution, the partnership received exchangeable shares through a distribution by Brookfield Infrastructure L.P. (“Holding LP”), or the Holding LP Distribution, of the BIPC exchangeable shares to all of its unitholders. As a result of the Holding LP Distribution, (i) Brookfield and its subsidiaries received approximately 13.7 million BIPC exchangeable shares and (ii) the partnership received approximately 32.6 million BIPC exchangeable shares, which it subsequently distributed to unitholders pursuant to the special distribution. Immediately following the special distribution, (i) holders of units held approximately 70.4% of the issued and outstanding BIPC exchangeable shares (ii) Brookfield and its affiliates held approximately 29.6% of the issued and outstanding BIPC exchangeable shares, and (iii) a subsidiary of the partnership owned all of the issued and outstanding class B multiple voting shares, or class B shares, which represent a 75.0% voting interest in BIPC, and all of the issued and outstanding class C non-voting shares, or class C shares, of BIPC, which entitle the partnership to the residual value in BIPC after payment in full of the amount due to holders of BIPC exchangeable shares and class B shares. The partnership directly and indirectly controlled BIPC prior to the special distribution and continues to control BIPC subsequent to the special distribution through its interests in the company. The BIPC exchangeable shares are listed on the New York Stock Exchange and the Toronto Stock Exchange under the symbol “BIPC”. i) BIPC exchangeable shares At any time, holders of BIPC exchangeable shares have the right to exchange all or a portion of their BIPC exchangeable shares for one unit per BIPC exchangeable share held or its cash equivalent based on the NYSE closing price of one unit on the date that the request for exchange is received, on a fixed-for-fixed basis. BIPC or the partnership, as applicable, has the ability to satisfy exchanges of BIPC exchangeable shares in units instead of cash. Additionally, the partnership has the ability to exchange all BIPC exchangeable shares for units at our election, on a fixed-for fixed basis. As a result of these characteristics, BIPC exchangeable shares have been classified as non-controlling interests in the Consolidated Statements of Financial Position. ii) Basic and diluted income per unit: The special distribution resulted in the issuance of approximately 46.3 million exchangeable shares. c) Brookfield Infrastructure Corporation Exchange Limited Partnership On April 21, 2021, Brookfield Infrastructure Corporation Exchange Limited Partnership (“BIPC Exchange LP”) was established by the partnership. In connection with the acquisition of Inter Pipeline Ltd. (“IPL,” “Inter Pipeline,” or “Canadian diversified midstream operation”), certain IPL shareholders were given the right to elect to receive, for each common share of IPL and in lieu of cash consideration, 0.25 BIPC exchange LP class B exchangeable limited partnership units (“BIPC exchangeable LP units”), or 0.25 BIPC exchangeable shares. The BIPC exchangeable LP units provide holders with economic terms that are substantially equivalent to those of a BIPC exchangeable share and are exchangeable, on a one-for-one basis, for BIPC exchangeable shares. Given the exchangeable features, we present the BIPC Exchangeable LP units as a component of non-controlling interest. d) Comparative figures In the current period, the partnership identified an immaterial error which has been corrected in the current period. The error relates to the classification of non-controlling interests within our Indian natural gas operations and our Indian telecom tower operation which should have been reported as liabilities in the amount of $0.1 billion in fiscal 2019 and $0.4 billion in fiscal 2020. As a result, approximately $0.4 billion that was previously reported within non-controlling interest attributable to interest of others in operating subsidiaries has been reclassified to financial liabilities within the Consolidated Statements of Financial Position in the current period. The comparative figures have not been corrected to reflect the effect of the above adjustment. The partnership has concluded that this reclassification error is immaterial and has no impact on the Partnership’s historical audited Consolidated Statements of Operating Results, Consolidated Statements of Comprehensive Income, and Consolidated Statements of Cash Flows
